IMPROVEMENT IN MAGAZINE HEATING Auncoolune STOVES.

Specification forming part of Letters Patent No. 192,864, dated July 10, 1877; application filed I r May 17, 1877.

i To all whom it may concern Be it known that-I, ERNST A.;O. Fox, of

and useful Improvements in Outstanding- Y Stoves; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a vertical section of a stove showing my improvements, and Fig. 2 is a similar view of a modification thereof.

Similar letters of reference in the accompanying drawings denote the same parts.

My invention has for its object to secure a 7 more thorough radiation of heat from the lower and rear part of the stove, to enable such radiation to be perfectly controlled and adjusted, and to combine with the ordinary out standing heating-stove an efficient and convenient heating and cooking attachment for use when occasion may require. To these ends the invention consists in a new and improved I construction of the escape fines and passages whereby the smoke and volatile products of combustion pass off through the chimney for the purpose of utilizing the entire base of the stove for heating purposes, and combining with such construction a rear extension or attachment, in which may be arranged ovens or heating-chambers, for the-purposes above indicated.

g In the drawings, A represents the combustion-chamber, B the fuel-magazine, O the fire-pot, D the gate, and E the ash-chamber,

- of an ordinary outstanding magazine-stove.

All the parts above mentioned are construct ed in the usual and well-kn0wn manner, except the combined grate and clearing attachment, which form the subject-of a separate application for Letters Patent, now pending in my behalf in the Patent Office.

The base of the stove is made somewhat deeper than usual, and is divided by a horizontal partition, f, into two compartments, F F. At the rear side of the stove is a vertical flue,G, extending from the partition f to the middle or. upper portion of the combustionchamber, said flue communicating with the combustiou chamber through an opening, 9,

.70, is provided in the and with the upper base-chamber F'through an opening, g.

ing closed in whole or in part by a damper, H. At the rear of the flue G-is a vertical chamber, I,extending from the top of said flueto the bottom of the stove, and communicating with the base-chamber F through an opening, i, and with the chimney through a pipe or collar, 6. An opening, provided with a damper, partition that separates the flues'G I, and directly in rear of the opening g, and a similar opening and damper, k, are arranged in the lower end of said partition, in rear of the opening g. Heating-chambers L, provided with suitable shelves and doors, may be arranged within the flue or chamber I, and an ash-slide, 7', may be placed at the lower rear edge of said flue.

The operation of this improved stove is as follows: In making the fire the dampers H k are closed, and the damper It opened, which gives a direct draft from the combustionchamber to the chimney. While the dampers are thus arranged there will be little orno radiation of heat from base of the stove, and the ovens L can be used only for warming purposes. When, for any reason, the direct draft is no longer desirable, the damper k is to be closed, whereupon the smoke and heated gases will be caused to dive through the flue G, either into the base of the passages g h, and thence to the chimney through the flue I, or else from the flue G directly into the flue I by accordingly as it may be desirableto make a greater or less heat in the ovens or in the base of the stove. Thus, it will be observed'that wh'enthedamper H is closed and k opened the heat will be directed mainly upon the ovens, while if the damper k is closed and H opened the heat will first radiate, to a considerable extent, from the entire base of the stove, and then the partially-cooled currents will pass to the flue I, where their action upon. the ovens will be less powerful. The dampers may, of course, be partially opened, more or less, so that the radiation of the heat from the base and rear of the stove and into the chambers "L can be perfectly controlled and adjusted at will.

In the front part of the partition f there is an opening, h,'capable of bestove through the wayof the passage is,

Ihaveshowna magazine base-burnin g stove in connection with my improvements, but, as they do not relate to the supply of the fuel, it is obvious that they may-be employed with v any other form of stove without departing from cal area'ot' the base, and communicating with each other by a front dampered opening, h,

the upper chamber communicating with a revertible flue, G, and the lower chamber with theflue leading to the chimney, substantially as described. r

2. Thecombination of the enlarged flue I and heating-chambers L L with the chambers F F, the revertible flueG, and the damperconnections, substantially as described.

3. In a stove, the combination, with the flue:

I and heating-chambers L L, of a chamber, F, occupying the entire bottom area of the stove,

*and through which'the Volatile products of combustion can be directed to the flue I for the purpose of radiating from the base of stove, or'from which said products of combustion can be entirely excluded without otherwise afiecting the draft of the stove when it may be desirable to prevent the radiation of heat from the bottom, substantially as described.
